2 Claims.

This invention relates to improvements in ozonizers, and has for itsobject to provide an ozonizer, simple and compact in construction, andeflicient in operation.

In the accompanying drawing;

Fig. 1 is a perspective view of an ozonizer according to the inventionwith a battery connected thereto;

Fig. 2 is a vertical sectional view of the 020- nizer shown in Fig. 1 inlarger scale with the battery connected thereto; and

Fig. 3 is a cross sectional view on line III-Ill of Fig. 2.

Referring to the drawing, I represents a casing provided with anintermediate partition 2 and a bottom member 3 to form an upper chamber4 and a lower chamber 5. The casing is also formed with a number ofperforations 6 and 'I in the side of the upper and lower chambersrespectively. The partition and the bottom are made of an insulatingmaterial, such as ebonite, Bakelite or the like. A cylinder 3 ofaluminium is securely mounted in the upper chamber 4 on the partition 2,which is painted with a paint non-corrosive for aluminium and is coatedwith a surrounding mica cylinder which in turn is coated with asurrounding cylinder III made of nickeled brass wire networjr. A silverwire II is arranged around the outer cylinder II). A base member I2 ofan insulating material is securely mounted in the lower chamber 5 at asuitable distance from the bottom 3 by means of supportsi3 secured onthe said bottom.

An induction coil I4 is securely mounted in the lower chamber 5 on thebase I2, of which the core and primary and secondary coils are indicatedat I5, I5 and I1 respectively. A spring I3 is at one end secured on theunderside of the base l2 by means of a spacer member l9 and a screw 20,the free end of the spring carrying an armature 2| and a contact piece22. Another spring 23 substantially of a U-shape is at its one armsecured to the bottom 3 by means of a bolt 24 and a nut 25, the otherarm carrying a contact piece 26 and being adjustable by means of anadjusting screw 21 passing through a threaded hole 23 of the bolt 24 toadjust the gap between the contact pieces 22 and 25.

The primary coil I6 is at one end connected to the positive terminal ofa source of electricity, such as a battery 29 through a conductor 30,the contact piece 22, the contact piece/26, the spring 23, conductors 3iand 32, a switch 33 and a conductor 34, the other end being connected tothe negative terminal of the battery by a conductor 33. A condenser 36is inserted between and across the conductors 30 and 32. The secondarycoil I1 is at one end connected to the aluminium cylinder 3 byaconductor 31, the other end being connected to the silver wire II by aconductor 35. A container 39 of a meshwork for perfumery is supported inthe top of the casing I.

In operation, the switch 33 is closed, and then a current of highvoltage is generated in the secondary coil by induction, which producesan electric discharge between the cylinder ll of brass wire networkforming a positive electrode and the aluminium cylinder 8 forming anegative electrode, whereby ozone is continuously produced and diflusedthrough the perfumery container 39 of a meshwork on the top of thecasing I and the perforations 6 in the upper chamber 4. The perforationsI in the lower cham ber 5 provide the passages for circulation ofcooling air in the lower chamber 5 enclosing the induction coll It.

It will be understood that the casing I may be formed of two separateparts, one corresponding to the upper chamber 4 and the other the lowerchamber 5, within the scope of the invention.

I claim:

1. In ozone producing apparatus, a cylindrical metal casing, a partitionof insulating material dividing the interior of said casing into a firstchamber and a second.chamber, an end member mounted in the end of'saidcasing and substantially closing said first chamber, a plurality ofmounting posts rigidly mounted within said first chamber upon said endmember, a mounting member of insulating material rigidly carried by saidmounting posts in spaced relationship with respect to said end member,magnetic core means rigidly carried by said mounting mem- -ber andhaving a pole face exposed toward said end member'at the central portionof said mounting member, armature means resiliently mounted on saidmounting member in cooperating relationship with respect to said poleface whereby the magnetization of said core means effects the movementof said armature toward said pole face and the demagnetization of saidcore means results in the movement of said armature away from said poleface, a pair of cooperating contacts one of which is mounted to movewith said armature means and the other of which is mounted upon saidmember, means adjustably mounting said other contact and providing anelectrical contact therewith comprising a threaded stud extendingthrough said end member in alignment with said other contact and anangular leaf spring having a fixed end attached to said end member and afree end to which is rigidly attached said other contact, and inductioncoil means on said core means electrically connected to be energized bythe engagement of said contacts with each other.

2. Apparatus as described in claim 1 wherein said induction coil meansis a high potential transformer having it's;primary winding connectedelectrically in. series with said contacts, and a condenser monnt edlwithin said first cham- :gaert and electrically connected across saidconac s.
